    Is Lablab (Seem) seed dangerous to eat? I grew up eating Seem in Bangladesh, and love it. Now I live in USA and found Seem beans (split seed) in Indian Grocery Store. However, Google says it can be toxic to eat if not boiled and the boiled water not drained a couple of times. Please help explain this toxicity part, and its consumptions by humans for centuries. Thanks.

      Dear Wahid Choudhury,

      Thanks for your query! It is better to eat boiled seeds in various ways like curry. Green or fresh seeds may cause indigestion and better to avoid.
